Application iiled- November 1, 1921. Serial No. 511,993.-

State oi Pennsylvania9 have invented cer#` tain new and luuseiul improvements in Attachments 'for Automobile Radiators, olii which the following is a speciiication.

Some ot the objects et the present invention are to provide an improved means ior preventing the cooling fluid of an .automobile engine from freezing; to provide a heater for automobile radiators which does not interfere with the proper functioning oi such radiator when the automobile is moving; to provide a heater for automobile radiators wherein air to be heated is caused to traverse a maximum distance while being heated in a relatively small heating chaine ber; to provide a heater arranged to become a permanent part oi an automobile radiator in cold or freezing weather, whereby the automobile can be left on the street or outdoors without danger of freezing; and to provide other improvements as will herein-A after appear.

ln the accompanying drawings, Fig. 1

represents a 'liront elevation of the radiator oi" an automobile equipped with a heater embodying one form of the present invention;

Fig. 2 represents an elevation oit the heater with the iront removed to show the interior construction; Fig. 3 represents a section on line BMS of F ig. 2; and F ig. l represents a detail ot the burner construction.

Referring to the drawings,"one iorm of the present invention consists of a easing 1() formed of sheet metal andgenerally ot rectangular shape, the length oi' which approximates the width ot a standard automobile radiator 11. lt will be understood that the shape and size ol the casing 10 can be made suitable for dil'ierent sized radiators so that the heat developed will be sutiioient to main-k tain a temperature high enoughto prevent the water in the radiator :from freezing. The casing 10 is arranged to be rigidly held in place as a permanent winter attachment by plate 12 and bolts 13 secured to the chassis frame 14C or any other suitable part, but is removed in weather which does not warrant its use.

ln the preferred form the casing l0 'forms a completely enclosed chamber 15, the rear wall 16 of which is provided -with outlets or pertorations 173 the function of which is to convey the hot-air and products lof combustion to the radiator 11. ln this connec tion it willbe noted that the height ot the perforated wall 16 isfsubstantially less than the height of the radiator to which the casing 1() is attached, so that a suiiicient area of radiator surface is exposed for proper running conditions in cold weather.

For the purpose ot heating the air circulated within and through the casing 10,` a heater is providedpreferably in the forni of a reservoir 2O 'or oil having a burner 2l of the wick type. @ne end ot the reservoir 20 is provided with a iilling inlet 22 which opens into a waste illed compartment 23 separated `by an open work partition 24 vfrom the main oil containing portion of the reservoir 20. This insures a leak-prooi construction so that none o' the oil can splash or work` out of the reservoir 20 when the automobile is in motion. rlhe bottom 25 of the casing; 10 is provided with air inlets 26 to promote circulation and combustion7 and also has attachedzthereto spring clips 27.

`These `clips 2T are spaced apart to receive between them the reservoir 20 andare ar- `inrcged to interengage with laterally disposed lianges 28, whereby the reservoir is rigidly held in place.

For the purpose of utilizing the full heating` value of theburner 21 `and causing a tortuous circulation of the heated air, the chamber 15 is provided with two inwardly projecting, upwardly inclined baliies 30 rigidly threatened respectivelyto two opposite side walls oi? the casing, the vjuxtaposed encs or said battles 3() being` spaced topermit certain of the products oi combustion to pass lbetween themy while other of the products are deflected to pass through the outlets 1? into contact with the lower portion oiE the radiator 11. Directly above the burner 21, and in the path of the rising heated products, is a transverse plate 31 horizontally disposed and having two downwardly inclined end wings 82, which terminate respec tively in close proximity to the side walls oit the casing 10. This plate 231 causes the lnfoducts oi combustion to be deflected laterally, in both directions, and downwardly, to rise around the ends of the wings 32, thereby prolonging the path ot' the air and causing it to be raised to a relatively high temperature. As the plate 31 is directly in the heat zone of the burner 21, it is maintained in a highly heated condition and heated to the desired temperatures,

l sists materially in the heating oi the air passing; through the casing l0 To further retard the heated air, a deiiector with inclined side portions cated adjacent the top oli' the casing l0 to receive the rising hot products and cause them to again -be deflected laterally and downwardly.

Thuskby the provision oit a series ot superpo'sed plates, or batlles, the air is thoroughly while the dimensions of the casing' l() are thus kept within limits which do not interfere with the successful operation ol the radiator ll.

ln order to gain access to the casing' l0 to light the burner 2l or to replenish the reservoir 20, the liront ol? the case is apen tured and has a hinged door which is provided with asuitablc locl'ring;` latch 35 desinned to hold the door tightly closed ui ler all operating conditions.

lreterably the reservoir Q0 is lilled with specialr oil tor burning purposes, one which is not explosive or quickly inflammable and which burns slowly with a maximum heatingr etl'ect.

lt is preferable to line the interior ot the casing l0 with asbestos 3 or any other suitable heat retaining means whereby loss oi heat by radiation through the casing walls reduced to a minimum.

F rom the toreg'oing it will be apparent that' a complete unitari: heating` means 'for automobile radiators has 'been provided which `can be applied to any type oit radiator ijn-such a. manner to permit the radiator to function perfectly as -a cooling means when the automobile is running in winter ,veather, and also to entirely prevent 't'rcezing ot the cooling fluid when the automobile is stationary.

Further, the air which through the casing` l() is given tortuous path whereby it s the `itull value oli the heat units from the burner 2l. and delivered against the lower portion oil the radiator ll hot and effective 'for the purpose intended.
